the filter @@||gamestar.de/js/gamestar/my_ad_integration.min.js$domain=gamestar.de

was added, mentioning this gamestar URL http://www.gamestar.de/videos/specials,20/oculus-rift,86946.html as the reason.
When deactivating this whitelist filter in Firefox (with ABP and only EasyList + EasyList Germany enabled), I could not reproduce any issue with playing the video.
So please remove that filter as it seems to be outdated.

Another reason why I want this whitelist filter removed is the following, though it should be irrelevant if the whitelist filter is not needed anyway:
Whitelisting that script actually breaks loading videos in uBlock (at least in Chromium, with some of ubo's own filters that circumvent the anti-adblock mechanism), e.g. on this page http://www.gamestar.de/spiele/watch-dogs-2/artikel/watch_dogs_2,52381,3303008.html, clicking the video preview image just makes the preview image disappear, but no video player appears.
The rule ||gamestar.de/js/gamestar/my_ad_integration.min.js^$important (i.e. disabling the whitelist filter) fixes this issue in uBlock Origin.

When you're at it, please also remove @@||gamepro.de/js/gamepro/my_ad_integration.js. That script isn't even embedded anymore, and as you can see videos on gamepro.de load fine. (They use gamepro.de/js/gamepro/my_ad_integration[b].min[/b].js now, but no reason to whitelist that.)
(I post that in this thread as gamepro.de is from the same company as gamestar.de and apparently uses the same software.)

Is this list still being maintained? I described a problem in detail and gave a simple solution.
Would it help if I did a pull request on GitHub?

Also please note that the first post in this thread as it currently appears wasn't written by me that way, but was edited by some third party and wasn't marked as such. The edits include the way links were presented (which is kind of ok, had it been marked as edited), but also changed grammar and words to misrepresent the meaning of my original sentences (e.g. mentions to uBlock Origin were removed, and in another instance "uBlock Origin" was replaced by "ubo"). Refer to the following link for how my first post appeared originally: http://pastebin.com/raw/eQLEQZDL (I urge the moderators and others with such privileges to not replace that link by a fake one.)
